It’s all about the Institutes in today’s UK Arabidopsis Research Round-up! New work this week comes from the John Innes Centre, the Sainsbury Laboratory, Rothamsted Research – and theEuropean Bioinformatics Institute, part of the European Molecular Biology Laboratory (EMBL-EBI) based in Cambridge, makes an appearance too.
- Wirthmueller L, Roth C, Fabro G, et al. Probing formation of cargo/importin-a transport complexes in plant cells using a pathogen effector. The Plant Journal, 17 November 2014. DOI: 10.1111/tpj.12691.
With collaborators in Germany, researchers from the John Innes Centre and the Sainsbury Laboratory in Norwich deduce that complexes between the adapter proteins importin-a, and the cargo proteins they recruit for active nuclear transport, are formed dependent upon cargo specificity, variation at the importin-a nuclear localisation sequence-binding sites, and tissue-specific expression levels of importin-a.
- Hsiao A-S, Haslam RP, Michaelson LV, Liao P, Chen Q-F, Sooriyaarachchi S, Mowbray SL, Napier JA, Tanner JA and Chye M-L. Arabidopsis cytosolic acyl-CoA-binding proteins ACBP4, ACBP5 and ACBP6 have overlapping but distinct roles in seed development. Bioscience Reports, 21 November 2014. DOI: 10.1042/BSR20140139.
This Bioscience Report included a number of researchers from Rothamsted Research, and explores the previously poorly understood roles of three cytosolic acyl-CoA-bding proteins (ACBPs). Microarray data revealed that all three are expressed in seeds, but further analysis in transgenic Arabidopsis revealed overlapping, but differing physiological effects on seeds.
- Cubillos FA, Stegle O, Grondin C, Canut M, Tisné S, Gy I and Loudet O. Extensive cis-regulatory variation robust to environmental perturbation in Arabidopsis. The Plant Cell, 26 November 2014. DOI: 10.1105/tpc.114.130310.
Led by a French team, this study also involved Oliver Stegle from EMBL-EBI in Cambridge. Using drought stress as an example of environmental variation, the aim here was to produce a detailed map of the ways in which cis- and trans-acting factors affect gene expression and responses to environmental conditions in Arabidopsis thaliana.
